Start in Libreville in the top left corner. Click the only bordering tile showing a non-european capital. Can you make it all the way through the maze without clicking a capital that belongs to a country from Europe?
You are not allowed to go diagonal
It only works if the tiles are divided into 5 COLUMNS (could be different on mobile devices)
Careful: Only click non-european capitals in the path from the top left to the bottom right
Read the caveats!
